Description

Technical Field

[0001] The utility model relates to the technical field of bearing marking, in particular to a laser marking machine for bearing processing. Background Art

[0002] Laser marking machines use laser beams to permanently mark the surfaces of various materials. The effect of marking is to expose the deeper layers of material by evaporating the surface layer, thereby engraving exquisite patterns, trademarks, and text. When processing bearings, laser marking machines are also required to engrave the bearing model and trademark on the bearing.

[0003] The existing patent with authorization announcement number "CN212122114U" discloses a bearing laser marking machine, which consists of a feeding conveyor, a small end face laser marking station, a bearing turning station, a large end face laser marking station and a discharge conveyor. A support plate is provided at the bottom of each station. A laser marking machine A is provided at the small end face laser marking station, a laser marking machine B is provided at the large end face laser marking station, a robot A is provided between the small end face laser marking station and the bearing turning station, and a bearing turning mechanism is provided at the bearing turning station. The machine has the advantages of improving product marking quality, increasing the laser marking pass rate, and improving work efficiency.

[0004] The existing patent with authorization announcement number "CN208195937U" discloses an intelligent double-sided laser marking machine, including a support table and an integrated electric control cabinet. The top and bottom of the support table are installed with a liftable platform, and the liftable platform is provided with a laser marking head. The liftable platform and the laser marking head are respectively connected to the integrated electric control cabinet. The support table is provided with an inclined two-dimensional manual translation stage, which adopts a dual laser marking head design to synchronously laser mark the inner and outer rings of the bearing from top to bottom; the laser marking head and the two-dimensional manual translation stage adopt an inclined design to prevent the anti-rust oil of the bearing from dripping onto the laser galvanometer lens of the laser marking head. The inclination angle is consistent to ensure that the laser galvanometer lens and the two-dimensional manual translation stage always remain in a horizontal state; the utility model has a simple structure, high stability, reasonable design, and is easy to implement.

[0005] When using the above-mentioned marking machine, only one person can operate one device, and the material needs to be manually placed on the marking station, which makes the material placement and retrieval efficiency slow. In addition, our company's original marking station uses the laser double-sided marking machine with the above-mentioned announcement number "CN208195937U". During the manual operation process, the marking position is inaccurate, resulting in a certain amount of defective products. The manual control of the marking position will reduce the qualified rate of finished products. Utility Model Content

At this time, the movable rod can drive the electric contact block B to contact the electric contact block A, automatically starting the indicator light to light up, to remind the staff that the bearing is fixed. If the indicator light fails to light up, it means that the bearing fixing position is offset. The staff can discover it in time to prevent the marking position from deviating, thereby improving the marking accuracy and reducing the number of defective products.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5, the utility model provides an embodiment of a laser marking machine for bearing processing, comprising a shell 1, a processing table 2 is arranged inside the shell 1, a hand-adjustable lifting platform 3 is arranged in the middle of the top of the processing table 2, two groups of markers 4 are slidably arranged on the hand-adjustable lifting platform 3, and a laser marking head 5 is arranged on one side of the two groups of markers 4. The two groups of laser marking heads 5 are symmetrically distributed and can mark both sides of the bearing at the same time. A marking platform 8 is arranged in the middle of the top of the processing table 2, and a marking hole 15 is opened on the inner side of the marking table 8. A discharge conveyor belt 9 and a feed conveyor belt 10 are respectively arranged at both ends of the top of the processing table 2, a mechanical arm 7 is arranged on one side of the top of the processing table 2, and a clamping claw 6 is arranged on the mechanical arm 7. A clamping block 11 is arranged at the bottom inside the marking table 8. The shape of one side of the clamping block 11 is arc-shaped, which can perfectly fit with the outer ring of the bearing, thereby improving the clamping stability. An in-place warning component is provided on the top of the clamping block 11.

[0024] Furthermore, the in-place warning component includes a warning light 12, a guide groove 13, an electric contact block A14, a groove 16, an electric contact block B17, a spring 18, a movable rod 19 and a push block 20. A warning light 12 is provided on the top of the clamping block 11, a groove 16 is provided on one side of the clamping block 11, a guide groove 13 is provided on the side inside the groove 16, a movable rod 19 is sleeved on the inner side of the guide groove 13, a push block 20 is provided on one side of the movable rod 19, and an electric contact block B17 is provided on the other side of the movable rod 19, an electric contact block A14 that cooperates with the electric contact block B17 is provided on one side of the inner side of the guide groove 13, and a spring 18 is sleeved on the outer side of the movable rod 19, which can remind whether the bearing is fixed in place to prevent deviation in the marking position.

[0025] Furthermore, a door is provided on one side of the shell 1, and an observation window is provided on the door, which is convenient for observing the working conditions inside the shell 1 and facilitating maintenance of the machine.

[0026] Furthermore, through grooves are provided at both ends of the housing 1 to match the discharge conveyor belt 9 and the feed conveyor belt 10, providing installation space for the discharge conveyor belt 9 and the feed conveyor belt 10, thereby facilitating the feeding and discharging of bearings.

[0027] Working principle: When marking a bearing, the operator only needs to place the bearing to be processed on the feed conveyor 10. After the bearing is conveyed to the housing 1 by the feed conveyor 10, the robot arm 7 can control the movement of the clamping jaw 6 to clamp the bearing. After clamping, the bearing is moved to the marking table 8. The robot arm 7 pushes the clamping jaw 6 toward the clamping block 11 so that the clamping jaw 6 and the clamping block 11 can clamp the bearing at the top of the marking hole 15. Then, the two sets of laser marking heads 5 can mark both sides of the bearing simultaneously, which improves the marking efficiency.

[0028] When the clamping jaws 6 and the clamping block 11 clamp the bearing, one side of the bearing can push the push block 20 to overcome the elastic force of the spring 18 and retract it into the groove 16. At this time, the movable rod 19 can drive the electric contact block B17 to contact the electric contact block A14, and automatically start the warning light 12 to light up to remind the staff that the bearing is fixed. If the warning light 12 fails to light up, it means that the fixed position of the bearing is offset, and the staff can find it in time to prevent the marking position from deviating.

[0029] After the bearing is marked, the bearing can be moved to the discharge conveyor belt 9 by the robot arm 7 and placed down to complete the discharge of the bearing.
